Question

把小数化为分数0.875=+13.75=+0.72=+8.06+=8.5=+0.16=？

Answer 1

0.875=875/1000=（875÷125）/（1000÷125）=7/8=8分之7
13.75=1375/100=（1375/25）/（100÷25）=55/4=4分之55
0.72=72/100=（72÷4）/（100÷4）=18/25=25分之18
8.06=806/100=（806÷2）/（100÷2）=403/50=50分之403
8.5=85/10=（85÷5）/（10÷5）=17/2=2分之17
0.16=16/100=（16÷4）/（100÷4）=4/25=25分之4
